Abstract
For the safeguard of bit streams of H.264 video codec, a new method was offered by this paper. In this document an optimized way of producing motion parameters is suggested. An extremely secure encryption system for H.264 codec can be proposed by encrypting this optimized motion parameter. The video compression is carried out with the help of adaptive PSO (Adaptive Particle Swarm Optimization) algorithm to obtain the best motion parameter in the elastic motion model of H.264 codec. Using ECC (Elliptic Curve Cryptography) algorithm the motion parameters are optimized and which are next encrypted to encrypt the optimized motion vectors. The Encrypted motion vector is specified as input for coding stage of H.264, which generates an encrypted bit stream. Using Matlab working platform the suggested system is reproduced. The comparisons are made over the presented H.264 codec with the suggested H.264 codec.
